成分数据的统计分析的许多工作都集中在解释与零相关性，独立性，除了约束，F-有界变量的独立性，在平均值和中位数的中立性测试的分类比例之间的相关性的困难。本文的问题的适当性的比例的依赖结构的特点，这些概念，提出了一种替代方法的建模，开发必要的分布理论和测试，并说明了方法的应用。
Much work on the statistical analysis of compositional data has concentrated on the difficulty of interpreting correlations between proportions with an assortment of tests for nullcorrelations, for independence except for the constraint, F-independence of bounded variables, neutrality in the mean and in the median. This paper questions the appropriateness of characterizing the dependence structure of proportions in terms of such concepts, suggests an alternative method of modeling, develops necessary distribution theory and tests, and illustrates the methodology in applications.
